A: Solar system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels;one or more batteries; a charge controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.

Q: How long do photovoltaic (PV) systems last?

A:PV system that is designed, installedand maintained well will operate for more than 20 years.The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly.Experience hasshown that most problems occur because of poor or sloppy system installation.

Q: What’s the difference between PV and other solar energy technologies?

A: There are four main types of solar energy technologies:

1. Photovoltaic (PV) systems, which convert sunlight directly to electricity by means of PV cells made of semiconductor materials.

2. Concentrating solar power (CSP) systems,which concentrate the sun’s energy using reflective devices such as troughs or mirror panels to produce heat that is then used to generate electricity.

3. Solar water heating systems, which contain a solar collector that faces the sun and either heats water directly or heats a “working fluid” that, in turn, is used to heat water.

4. Transpired solar collectors, or “solar walls,” which use solar energy to preheat ventilation air for a building.

Q: Can I use RG Solar Home system to power my house?

A: Yes. RG Solar Home System can be used to power your entire house with all electrical systems, including lights, Fan, TV, and Other appliances. RG offeres various options to choose the customer based on there requirement & budget. Please approach the RG energyconsultants to suggest & choose the exact system for your requirements.

Q: Can I use RG Solar Power plant system to power my business Place?

A: Yes. RG solar power plant systems can be used for commercial buildings, industries & Factories.It will reduce there energy bills & generate the energy required for there energy needs.In long team it make huge financial benefit to the customer. Please approach the RG energy consultants to suggest & choose the exact system for your requirements.

Q: How big a solar energy system do I need?

A: The size of solar system you need depends on several factors such as how much electricity or hot water you use, how, the size of your roof, and how much you’re willing to invest. Also,do you want the system to supply your complete energy usage or to supplant aportion of your higher cost energy usage? You can contact our system designer/installer to determine what type of system would suit your needs.

Q: What are the environmental benefits?

Solar energy creates electricity and heat and avoids pollution from conventional coal plants and nuclear plants. Using national average emission factors,every megawatt-hour of electricity generated through a solar PV panel avoid more than 590Kg of carbon dioxide (CO2),more than 2.25KG of sulfur dioxide (SO2) and almost 1Kg of nitrogen oxide (NOx) and it also avoids producing radioactive nuclear wastes.

Solar energy production is highest on hot,sunny days when air conditioners are running and electricity demand peak. By providing energy during peak demand times, solar provides a clean alternative to ‘peaking plants’, that are often the dirtiest and least efficient coal and oil plants.

Q: Why do I need a Charge Controller?
A: A charge controller regulates the charge on the batteries, giving full power when necessary and reducing the charge as the batteries require less. This is important for maintaining the health of the batteries.

Q: What is a PWM charge controller?
A:PWM stands for Pulse Width Modulation and is basically a 3 stage charging cycle type controller. Most decent charge controllers use this technique.

Q: What is a MPPT charge controller?
A: MPPT stands for Maximum Power Point Tracking.This is a newer type controller that not only provides
multi-stage charging, but it also delivers more power to the batteries by matching the battery voltage to the solar panel voltage. This makes them more efficient especially in varying levels of sunshine. They also cost a little more.

SOLAR THERMAL

Q: How does a RG solar water-heating system work?

A: RG solar water-heating system features a solar tube collector that faces the sun to absorb the sun’s heat energy. This collector can heat water directly. RG Solar Water heaters is highly efficent to heat the water with in 3-4 hours of good sunlight.

Q: What are the benefits of using solar energy to heat water in my home?

A: First, the fuel is free! Once you recover the initial costs of a solar system through reduced or avoided energy costs (that is, lower utility bills), your solar system will require expenditures only for rare maintenance. The system will work more than 10 years & give the hot water free of cost.

Solar water heaters and other solar technology applications do not pollute. They do not add to the carbon dioxide , nitrogen oxides, sulfur dioxide and other air pollutants and wastes produced by most of today’s power plants,even those that run on natural gas. And they allow you to burn less natural gas in your home, as well.
